This invention relates a concrete building Structure and to a concretewall structure. 1 In modern concrete buildings it is often desirable to have a space or opening in 'thewall forventilating and insulating purposes. It is desirable, therefore, to have simple and eflicient means for forming such a space inthe wall. which at the same time will not weaken the wall structure.

It is an object of this. invention, therefore, to provide a simple and efficient struc-J ture of wall having an opening therein.

It isanother object of the invention to proopen mesh material adapted to hold the conci'ete together with suitablefspacing means for said frame. v

These and other objects and advantages of the invention will be fully set forth in the following description made in. connection'with the ac'con' panying' drawings, in which likereference characters refer to siniilar parts throughout the several views and in which e Fig. 1 is a vertical section through the wall of a building, showing a portion of the roof and floor structure;

Fig. 2 is a view in front elevation of one of the wall frames, showing a portion of the openmesh material used;

Fig. 3 is a horizontal section through a portion of a building at the corner thereof; and i Fig. 4 is a horizontal section taken on line 4- 1 of Fig. 1, omitting the concrete portion of the Wall and shown on an enlarged scale.

Referring to the drawing, a section of a bulldingis shown in Fig. 1, compr sing the side wall designated generally as 5. The

lower orfirst floor of the building is indicated as 6,the same being shown as comprising two layers of boards or other material which are supportedupon a beam 7 which transverse dimension than the wall 5 and a horizontal layer 5 forming the floor of the basement is also shown. A section of earth 8 is shown atone side ofthe lower or foundation portion of the wall, the top surface of which is indicated as 8. The usual baseboards 9 are shown extending about thewall .just above the floor 6, a molding strip 10 also being shown disposed in the corner of the wall and baseboards. A portion of the window frame in the wall is shown comprising the inner sill. 11 and the outer sill portion 11', the window sash being shown as 12. The horizontal roof beams 13 areshown at the top of the wall 5, which support the rafters 14- on which is-placed the roof layers A cornice board 16 is also shown secured 1 15. to the horizontally extending members 17 which may comprise the usual 2 x 4 timbers. The wall 5 has a space or assage 5 formed therein at each side of which is disposed a frame While the frames 18 V ma be variously made, in the embodiment of the invention illustrated they are shown as each comprising"horizontally extending bars 18 extending in spaced relation and a set of bars18 also extending in spaced relation at right angles to the bars18". bars 18 and 18? is disposed a layer of open mesh material 18. This material may comprise any open mesh metal material of the character now used for holding concrete plaster or cement such as metal lathe or furring. In Fig. 2 a portion of this material is shown, the same comprising rows 18 of struck up tongues or projections from the metal. The frames 18 are spaced by a bolt or bar 19 having nuts or heads 20 on aging the bars 18. The bolts 19 have pro ecting threaded portions 19 extending through the frames 18, the same being provided with nuts 21 adapted to clamp the frames and engage the outer bars 18. The projectin ends 19 extend into the concrete portion 0 the wall as shown in Fig. 1.

When the wall is to be constructed, the frames 18 will be placed in position and the usual forms'built to confine the concrete. The concrete is then poured in the form and the same passes between the bars 18". The

concrete also penetrates the open mesh layer 18", passing therethrough and substantially covering the inner side thereof. The layer 18 and the bars 18" are thus embedded in the concrete layer so that the layer has a Between the strong firm and su porting bond on the frame 18. The wal is also supported by the projecting ends 19 of the bolts 19 whic form reinforcing members for the wall. The passage 5 is thus left in the wall and at the same time a very strong and durable wall is produced. While the spacing of the bars 18 and 18 may be varied, inpract-ice it has been found that if these bars are spaced two feet apart, that satisfactory re sults are obtained. 2

From the above defcription it is seen that applicant has provided a very simple and etticient structure of building and wall.

The wall comprises the desired air space and atthe same time is strong and durable and easily and inexpensivel constructed.

It Wlll,'0'f course, be understood that various changes may be made in the form,

details, arrangement and proportions of the parts, without departing from the scope of applicants invention, which, generally stated, consists in a device capable of carrying out the objects above set forth, in the novel parts and combinations of parts disclosed and defined in the appended claims.

\Vhat is claimed is 1. A concrete wall structure comprising spaced frames, each having spaced horizontal and vertical bars. a layer of open mesh material held between said bars, bolts con necting said frames and having enlarged .portions contacting the inner sides thereof holding the same in properly spaced relation and means on said bolts at the outer sides of said frames engaging the same and holding them in proper; position, the ends of said bolts projecting beyond said frames, concrete walls at theouter side of said frames surrounding said projecting ends,

tal and vertical flat bars, a layerofopen mesh material held between said bars, means extending between said frames and engaging the inner and outer sides thereof for holding said frames in spaced relation, a concrete layer disposed atthe outer side of each of said frames and enga ing said open mesh material and held ther y, whereby a Wall, is formed, comprising an air space between said layers. i c

3. A concrete Wall structure comprising spaced frames, each having spaced substan tially parallel" bars and other s aced substantially parallel bars secured t ereto and extending at an angle thereto, a layer of open mesh material held between said Sets of parallel bars, means connecting said frames and extending therebetween and having means at the inner and outer sides thereof for holding said frames in spaced parallel relation, a concrete layer disposed at the outer side of each. of said frames engaging said open meshed material and held thereby, the s ace between said frames being open and orming an air space between said layers. i

In testimony whereof I aflix my si nature.
